Flexible FloorLiner HP Construction
WeatherTech FloorLiner HP uses a rubber-like thermoplastic elastomer instead of the harder material found in the company’s traditional FloorLiner. It offers a softer feel while retaining raised edges and molded channels.
The TPE compound is engineered to resist:
- Extreme heat and cold
- Cracking
- Curling
- Material breakdown
- Everyday fluid exposure
- Repeated removal and cleaning
The material is also 100% recyclable and manufactured without latex, PVC, cadmium, or lead. Additional construction information is available from WeatherTech.
High-Wall Interior Protection
The laser-measured liners follow the contours of the Ram’s front and rear footwells. High walls extend around the floor area to contain water and debris that ordinary flat mats can allow onto the carpet.
Molded surface channels direct liquids toward lower containment areas, helping control:
- Mud and trail debris
- Snow, slush, and road salt
- Job-site dirt
- Sand and gravel
- Spilled drinks
- Pet messes
- Everyday carpet wear

Anti-Slip and Retention Features
The FloorLiner HP uses factory-compatible retention provisions, non-slip nibs, and a textured underside to resist movement. A watertight sill around the retention clasps helps prevent spilled liquid from passing through the mounting area.
Beveled edges reinforce the raised walls and reduce the chance of them folding inward. This is particularly important beside the accelerator and brake pedal, where liner movement becomes a safety issue rather than merely an annoyance.
Installation Instructions
Installation normally takes only a few minutes:
- Remove every original and aftermarket floor mat.
- Vacuum dirt and debris from the carpet.
- Position the driver-side liner in the front footwell.
- Attach it securely to the factory retention points.
- Install the front-passenger liner.
- Place the one-piece rear liner across the Crew Cab floor.
- Check the rear seat mounts and confirm that the truck does not have incompatible underseat storage.
- Verify unrestricted accelerator, brake-pedal, seat, and seat-track movement.
Never stack FloorLiner HP mats over existing floor mats. Improperly secured mats can interfere with the pedals.
Our OEM replacement parts guide covers why exact configuration matters when buying vehicle-specific components.
Cleaning and Maintenance
Remove the liners from the truck before washing them. Shake out loose debris, rinse with water, and clean stubborn residue with mild detergent or an approved floor-liner cleaner.
Avoid silicone dressings and greasy interior protectants. They make the mats shiny, slippery, and extremely prepared for a lawsuit.
Allow the liners to dry before reinstalling them. Periodically inspect the front retention points and check that the rear liner remains correctly positioned.
Frequently Asked Questions
What does WeatherTech 441428-1-2IM fit?
It fits compatible 2019–2024 Ram 1500 DT Crew Cab trucks with carpet and without factory rear underseat storage.
Does it fit a 2019 Ram 1500 Classic?
No. The Ram 1500 Classic uses the previous-generation DS body and requires different floor liners.
Will it fit a Quad Cab?
The complete 441428-1-2IM package should not be ordered for a Quad Cab. Its second-row liner is designed for the Crew Cab floor.
Does it fit trucks with rear underseat storage?
No. This version is listed for Crew Cab trucks without the factory underseat storage system. WeatherTech offers separately configured rear liners for trucks with storage.
Does engine size affect fitment?
Not normally. Cab style, body generation, flooring, and underseat storage are the critical fitment details.
Are these hard plastic liners?
No. FloorLiner HP uses flexible, rubber-like TPE. WeatherTech’s standard FloorLiner is the firmer alternative.
Does the package include a transmission-hump liner?
The one-piece second-row liner spans the compatible Crew Cab rear floor area. Always compare the product image with the truck’s actual floor and storage configuration.
Can factory carpet mats remain underneath?
No. Remove all existing mats before installation to ensure correct retention and pedal clearance.
Final Verdict
WeatherTech 441428-1-2IM is a strong all-weather option for a 2019–2024 Ram 1500 Crew Cab without factory rear underseat storage. It combines front and one-piece rear coverage with a flexible TPE construction that is easier to handle than a rigid liner.
The important part isn’t simply owning a “2019 Ram.” Confirm that it is the redesigned DT Crew Cab, has carpeted flooring, and lacks factory rear underseat storage before ordering.
